"Seinen"

Keiichi, the goddesses, and the motor club gang visit a family friend's house, and meet a woman named Chieko Honda, but she is a contemporary of Keiichi's grandfather, and had passed away. Could she be a ghost? The goddesses apparently think so, and Keiichi must figure out the reason she's still around and the loose ends she's trying to have resolved.
